MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641061511 A) filed by Sr University, Warangal, Telangana, on May 14, for 'trust adaptive clustered aggregate signature system for secure communication in a vehicular ad hoc network.'
Inventor(s) include Dr. Arun Sekar R; Bommineni Varshitha Reddy; Gujjaru Sanjay; and Endla Lathika.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A trust adaptive clustered aggregate signature system for secure communication in a vehicular ad hoc network comprises of multiple onboard units 101 101 generating cryptographic messages and local signatures, at least one roadside unit positioned along a roadway and configured to communicate with the plurality of onboard units 101, a secure communication processor 103 evaluating historical transaction accuracy to compute behavior based trust scores forming trust clusters based on score similarity and spatial proximity, aggregating cryptographic signatures into cluster aggregate signatures with weighted contribution from higher trust vehicles and verifying at roadside unit for authentication and malicious node isolation, a cloud platform 104 receiving trust alerts distributing blacklists and providing real time monitoring of trust variations and spatial attack distribution, a vehicle-to-everything communication protocol 105 enabling exchange between onboard units 101 and roadside unit performs batch verification, dynamic isolation threshold adjustment and computational offloading to optimize latency and security."
